Sea otters are a marine mammal native to the coasts of the northern
and eastern North Pacific Ocean. These shots, taken in Alaska, show
otters keeping warm as they go for a dip in the freezing cold. In one
photo, a baby otter sleeps on its mother as they float on a surface of
the lake which is surrounded by ice. (See first photo, below.)

These pictures were submitted to National Geographic's Your Shot, and
one photo of the sea otters (above) was published in National
Geographic magazine. As he states, excitedly, "Dreams come true in a
holiday season. I am little bit too old to believe in miracles... but my
small picture of the otters was really published in Dec 2014 issue of
National Geographic US, page 32. Many, many thanks to all my dear
friends around the world for fantastic support of this picture. Sincere
thanks to editors of NG for choosing this picture for publishing among
the millions of great images."
